The major issue with steel reinforced concrete is a corrosion induced shortened building life time. This cover image designed by Michael Sigrüner and colleagues depicts a SEM image of a polypropylene‐fiber abraded by a concrete mixing process, taken by Prof. Dr. Müller of the Rosenheim University. To identify leading mechanisms in the debonding process of polymer fibers embedded in concrete, selected fiber properties were correlated with their adhesion determined by a single fiber pull‐out test. The abrasion taking place in concrete mixing produces undercuts which acts in concert with the fibers mechanical properties to mechanically anchor the fiber within the concrete matrix.
